BOX-SEALING MACHINE.

Application filed December 31, 1923. Serial No. 683,655.

To all whom it may concern:

Be it known that I, JAooB P. VERHULST, a citizen of the United States, and resident of Sheboygan, in the county of Sheboygan and State of lVisconsin, have invented new and useful Improvements in Box-Sealing Machines, of which the following is a description, reference being had to the accompanying drawings, which are a. part of this specification.

This invention relates to box sealing machines, particularly adapted for sealing the ends of knock-down pasteboard shipping boxes or cartons.

In practice, shipping boxes or cartons of this characte are received in a knock-down or collapsed form, and when being prepared for use they are opened and the flaps at one end thereof are sealed. Thereafter the goods to be shipped are packed in the carton or box whereupon the other end is sealed. The device forming the subject matter of this invention is adapted particularly for sealing the first end of the box previous to packing.

The invention has for one of its objects to simplify the construction of devices of this character, rendering the operation of the same simple and efficient, and offering the possibility of manufacturing and maintaining the devices at a minimum cost.

The novel combination, construction and arrangement of parts will be made more apparent as this description proceeds, especial.- ly when considered in connection with the accompanying drawings wherein:

Figure 1 is a transverse sectional view of a machine constructed in accordance with this invention, the parts being shown in position to receive a box;

Fig. 2 is an enlarged fragmentary side elevation, partly in section, of one of the box receiving elements;

Fig. 3 is a similar view showing in addition a part of the frame structure, with the box receiving element in a different position;

Fig. 1 is a fragn'ientary sectional view. taken substantially on the plane indicated by the line 4-4 in Fig. 3; and,

Fig. 5 is a fragmentary sectional view, taken substantially on the plane indicated by the line in Fig. 3.

Referring now particularly to the drawings wherein like reference characters indicate like parts, it will be noted that the device consists essentially of a frame 10, upon which there is mounted a table 11, this table being employed as an abutment co-operating with the box receiving elements, and also as a support for storing quantities of the cartons or boxes in knock-down condition previous to scaling the ends thereof.

Associated with each frame and table there is preferably provided a plurality of box receiving elements 12, these box receiving elements being arranged at spaced intervals upon the frame 10 and so mounted as to co-operate with the abutment table 11 during the operation of the device. For the purpose of mounting the box receiving elements there may be provided a plurality of frame members 13, to. which there is secured, supporting members 14, one for each box receiving element.

By reference to Fig. 2 it will be noted that to each supporting member 14 there is pivoted, as at 15, a casting 16 having a tubular extension 16 threaded therein, this connection enabling each box receiving element to be swung from the position illustrated in Figs. 1 and 2 to the position illustrated in Fig. Telescoping within the casting 16 and tubular extension 16 is a rod or standard 17, the lower end of this standard being provided with an elongated slot 18. To the upper end of each standard there is secured a platen or box receiving platform 19 of the proper shape and dimension to fit snugly within the box 20. the flaps 21 of which are to be sealed, (see Fig. 1).

Pivot-ed to the casting 16 as at 22 is afoot treadle 23. an elongated portion 2a of this foot treadle being in operative engagement with the slot 18 formed in the lower end of the standard 17. Formed in the treadle 23 is a recess or notch 25 into which the lower end 26 of a locking lever 27 is adapted to be moved. This locking lever is pivoted, as at 28, to an arm 29. clamped around the tubular extension 16. Chains 30 attached to each box receiving element and preferably to the end of the arm 29 and also to a stationary part of the frame, limit the outward swinging movement of the box receiving elements, as will be apparent.

In practice, cement is applied to the flaps 21 of the box 20, after the box has been placed upon the platen or platform of the box receiving element. The box receiving and minimizing maintenance costs.

element is then swung about its pivot into the position illustrated in Fig. 3. At the same time the foot treadle 23 is operated, whereupon the standard 17 of the box receiving element is axially displaced, forcing the platform or platen 19 upon which the box is mounted upwardly against the abutment table 11, whereupon the flaps 21 are folded into closed position.

During the time the box receiving element is swung into'its upright position, the locking lever 27 is also swung to locking position, so that upon the depression of the foot treadle 23 the lower end 26 of the looking lever is moved into engagement with the notch or recess of the foot treadle, whereupon the box is held tightly clamped between the platen 19 ..-and the abutment table 11. The parts are permitted to remain inthis position until the cement has set, whereupon the box may be released by manipulating the locking lever 27 in the obvious manner.

As has been mentioned, it is proposed to associate with 'ea'ch 'frame 10 and table 11, a plurality of these box receiving elements, so that the operator can mount a box on each of the box receiving elements and clamp the same in place, this operation requiring suflicient time so that by the time the last box has been mounted and is clamped against the abutment table 11, the cement on' the first box'has set, whereupon this box may be removed and is ready to be packed, and another box placed upon this box receiving element. Thus the operation of sealing the first end of the boxes is practica'lly a continuous one. "As has been mentioned,"t-he top of the abutment table 11' may be employed for storing a large supply of the boxes in knock-down or collapsed condition within convenient reach of the operator."

'From the foregoingit will be immediately apparent that an extremely simple, practical and efficient device i s'provided for sealing the flaps of knock-"down boxes or cartons, the arrangement of the parts offering the possibility of efficiency in operation the maniifacturing and WVhi'lethe invention has been described herein in some detail, obvious modifications will suggestthemselves, and to this end reservation is made to make such changes in the details of construction and combination and arrangement of parts as will come within the purview of the accompanying claims.

Having thus described the invention what is claimed is:

1. In a box sealing machine, a table forming an abutment, a pivotally mounted box securing platform movable from box receiving to operative position, manually controlled means for moving said platform into engagement with said table, and means mounted on said platform and movable therewith for locking said platform in this position, said latter means being moved to operative position during the movement of said platform. v

2. In a box sealing machine, a table forming an abutment, a plurality of box receiving elements, each box receiving element in cluding aplatform adapted to receive a box to be sealed and a foot treadle for moving said platform into clamping position against said table.

3. In a box sealing machine, a table forming an abutment, a plurality of box receiving elements, each box receiving element including a platform adapted to receive a box to be sealed, a foot treadle for moving said platform intoclamping position against said table and a locking lever co-operating with said foot treadle for holding said pla'tform in clamping position.

4. In a box sealing machine, a table forming an abutment, a plurality of box receiving elements, each box receiving element in eluding a pivotal supporting casting, a standard telescoping into. said casting, a platform carried by said standard and adapted to engage the box, afoot treadle operatively connected to said standard whereby said standard and platform may be moved into clamping position against said table and a locking lever for locking said box receiving element in clamping position.

5. In a box sealing machine, a table forming anabutment, a plurality of box receiving elements, each box receiving element including a pivotal supporting casting having a tubular extension, at standard telescoping into said casting and extension, a platform carried by said standard and adapted to engage the box, a foot treadle operatively connected to' said standard whereby said standard and platform may be moved into clamping position against said table and a locking lever for locking said box receiving element in clamping position.

In testimony whereof, I affix my signa ture.

JACOB P. VERHULST.
